Cisplatin-induced azoospermia and testicular damage ameliorated by adipose-derived mesenchymal stem cells

Biol. Res; 56 (), 2023
BACKGROUND: The testes are highly susceptible to the adverse effects of chemotherapy and radiation at all stages of life. Exposure to these threats mainly occurs during cancer treatment and as an occupational hazard in radiation centers. The present study investigated the regenerative ability of adipose-...

Unexpected effect of testosterone in hypergonadotropic hypogonadism and nodular Leydig cell hiperplasia. Report of one case

Rev. méd. Chile; 150 (5), 2022
ABSTRACT We report a 27 -year-old male referred because of hypergonadotropic hypogonadism with low testosterone and azoospermia. At 23 years of age, he underwent an excision of a hypoechoic 0.7 cm nodule of the left testicle. The pathological diagnosis was a Leydig cell tumor. In the right testicle, ther...

Testosterona inhibe la actividad de la aldosterona sintasa silvestre y quimérica in vitro

Rev. méd. Chile; 149 (11), 2021
BACKGROUND: Familial hyperaldosteronism type I is caused by the generation of a chimeric aldosterone synthase enzyme (ASCE) which is regulated by ACTH instead of angiotensin II. We have reported that in vitro, the wild-type (ASWT) and chimeric aldosterone synthase (ASCE) enzymes are inhibited by progeste...

Testosterone activates glucose metabolism through AMPK and androgen signaling in cardiomyocyte hypertrophy

Biol. Res; 54 (), 2021
BACKGROUND: Testosterone regulates nutrient and energy balance to maintain protein synthesis and metabolism in cardiomyocytes, but supraphysiological concentrations induce cardiac hypertrophy. Previously, we determined that testosterone increased glucose uptake—via AMP-activated protein kinase (AMPK)...

The effect of testosterone replacement on intramedullary, inguinal and visceral fat in ovariectomized rats

Abstract Objective The present article aims to evaluate the impact of testosterone treatment on the expansion of visceral, subcutaneous and intramedullary adipose tissue of ovariectomized rats and the visceral and subcutaneous fat expression of peroxisome proliferator-activated receptors (PPARs) gamma....

Effect of testosterone on proliferation markers and apoptosis in breasts of ovariectomized rats

Abstract Objective To investigate the action of testosterone (T), isolated or associated with estradiol benzoate (EB), on the proliferation markers and apoptosis of breasts of ovariectomized rats. Methods A total of 48 castrated female Wistar rats were divided into 6 groups, and each of them were sub...

Effect of metformin on semen quality

Braz. j. pharm. sci; 52 (4), 2016
ABSTRACT Various studies have linked metformin, a universally antidiabetic drug, with semen quality; however, such a direct link has not been established. This review systematically addresses and summarizes the effect of metformin on semen quality, particularly sperm function. We searched the MEDLINE ele...

Arq. bras. cardiol; 107 (6), 2016
Abstract Background: Impaired angiogenesis in cardiac tissue is a major complication of diabetes. Protein kinase B (AKT) and extracellular signal regulated kinase (ERK) signaling pathways play important role during capillary-like network formation in angiogenesis process. Objectives: To determine the e...
